Exam 2V0-15.25 Topic 1 Question 42 Discussion

To convert an existing vSphere environment into aVMware Cloud Foundation (VCF) 9.0 Management Domain, several prerequisites must be met as defined in the VCF 9.x documentation.
First,VCF 9.0 requires vSphere 9.0as part of its Bill of Materials (BOM). The uploaded VCF 9.0 documentation confirms that VCF 9.0 is built onvSphere 9.0, vCenter 9.0, and NSX versions that align with the 9.x stack. A vSphere 8.0 Update 3 environment isnot supportedas a foundation for a VCF 9.0 management domain; therefore, the administrator mustupgrade the entire vSphere platform to vSphere 9.0 before VCF deployment.
(Reference: VCF 9.0 BOM - vSphere 9.0 is mandatory.)
Second, VCF management domain creation strictly requiresvSphere Distributed Switches (vDS). VCF does notsupportvSphere Standard Switches (VSS)for any management domain hosts. The VCF 9.0 design and deployment guides state that all ESXi hosts intended for a management domain must use vDS for management, vSAN, and vMotion networking. Therefore, the existence of a VSS must be corrected by deploying and configuring avSphere Distributed Switchand migrating host networking accordingly before Cloud Builder deployment.
Removing standalone hosts or removing a VSS from inventory isnot required. Only the hosts selected for the management domain need to be prepared.
Thus, the required changes are:
#B. Upgrade vSphere 8.0 Update 3 to vSphere 9.0
#C. Configure a vSphere Distributed Switch
These are the only changes explicitly required by VCF 9.0 documentation.
